SASH-LOCK.

SPECIFICATION forming part of Letters Patent No. 718,577, dated January 13, 1903.

Application filed August 29,1902. Serial No. 121,456. (No model.)

To' all whom it may concern:

Be it known that I, LEMUEL PATTERSON, a

citizen of the United States, residing at Vtarren, in the county of Warren' and State of Pennsylvania, have invented a new and useful Sash-Lock; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and. use the same. I

The invention relates to sash-locks; .and it has for its object to provide a simple, inexpensive, and efficient sash-lock adapted to be readily applied to windows having balanced or unbalanced sashes without necessitating the removal of the latter from a windowframe and capable of securely locking the sashes in their closed position and of holding the same at any desired adjustment.

A further object of the invention is to provide a sash-lock of this character which will be invisible from the exterior of the window adjustment of the sashes.

The invention consists in the novel con-v struction and arrangement of parts hereinafter described and shown, and particularly pointed out in the claim hereto appended.

In the drawings forming part of this specication, and in which like numerals of reference designate corresponding parts, Figure l is a perspective View of a portion of a window provided with a sash-lock constructed in accordance with this invention. Fig. 2 is a detail View of the catch of the upper sash. Fig. 3 is a detail View of the dog of the lower sash. Fig. 4 is a detail perspective view of the hollow ratchet-strip. Fig. 5 is a detail view of the blank from which the hollow ratchet-strip is constructed.

Referring to the drawings, l designates a hollow ratchet-strip approximately U -shaped in cross-section and constructed of a plate of sheet-steel or other suitable material of the form shown in Fig. 5 of thevdrawings, and .the said plate, with apertures 2 and 3 punched or otherwise formed in it, is folded at opposite sides of the center to form the hollow rectangular or approximately U -shaped ratchetstrip illustrated in Fig. 4 of the drawings. The hollow ratchet-strip, which is composed of two sides and a connecting transverse portion, is of the same size cross-sectionally as the parting strip or bead 4 of a window-frame 5, and in practice a section or portion of the said-parting strip or bead 4 is entirely removed, and the ratchet-strip is placed in the space or recess and forms a continuation of the adjacent portions of the parting strip or bead and completes the same. A portion of the bead may be thus removed without taking out the sashes from a window-frame. The ratchet-strip, which may be of any desired length to secure the desired adjustment of the sashes, is fastened to the window-frame by screws 6 or other suitable devices, which pass through perforations of the transverse portion of the ratchet-strip.

The apertures formed in the front side and the transverse portion of the ratchet-strip are rectangular, and the latter are engaged by a pivoted gravity-catch 7 of the upper sash 8, whereby the upper sash is locked in its closed position or at the desired adjustment. The catch 7, which is secured to the side rail of the upper sash bya screw Q or other suitable fastening device, is constructed of thin metal and lies close to the face of the 'side rail and is adapted to clear the lower sash, so as not to interfere with the complete adjustment or movement of the upper sash. The screw 9 passes through a countersunk perforation of the upper portion of the catch, and a washer 10 is interposed between the catch and the window-sash 8 to permit the former to swing freely. The catch, which is provided with a depending handle portion 11, has an inclined arm or engaging portion l2, arranged at an acute angle to the handle portion and adapted to project into the apertures 3 of the ratchetstrip. The handle portion, which is arranged approximately in a perpendicular position when the arm is in engagement with the ratchet-strip, is of greater weight than the said arm and is adapted toswing the same inward against the ratchet-strip, whereby the catch will engage the latter automatically when released. The handle is adapted to be swung outward to carry the arm away from the ratchet-strip to permit the upper sash to slide freely.

The apertures 2 at the front face of the ICO ratchet-strip are engaged by a lug 13 of an inclined dog 14', which is pivoted at its lower end by a rivet 15 to a perforated ear 16 of a plate 17. The plate 17, which is stamped outof sheet metal, may be constructed of any other suitable material and is secured by screws or other suitable fastening devices to the top of the lower sash 19. The dog, which is also preferably stamped from sheet metal, may be constructed of any other suitable material, and it is extended above the lug 13 to form a shoulder 20, which bears against the ratchetstrip above the adjacent aperture 2, into which the lug projects. The lug forms a hook and holds the lower sash against upward or downward movement, and it is maintained in engagement with the ratchet-strip by gravity. The inclined dog is provided between its ends with a laterally-projecting lip 21, adapted to be engaged by a finger to enable the dogr to be readily swung out of engagement with the ratchet-strip. When the dog is swung out of engagement with the ratchet-strip, the lower sash is permitted to slide freely.

The hollow ratchetstrip and the locking devices which engage the same may be finished of any desired metal and may be constructed either plain or ornamental.

The device is adapted to be applied to either balanced or unbalanced ashes and does not necessitate the removal of the same from the window and is invisible from the eX- terior thereof.

A device of the class described, comprising a ratchet-strip cross-sectionally of the same area as the parting bead or strip of a Windowframe, designed to be mounted in a recess or cut-away portion of the said parting strip or bead to form a continuation of the same, and locking devices mounted on the sashes for engaging the ratchet-strip, substantially as described.

In testimony whereof I have hereto affixed my signature in the presence of two witnesses.

LEMUEL PATTERSON.
